GASOMETER.

Specification of Letters Patent No. 21,887, dated October 26, 1858.

To all whom it may concern:

Be it known that I, Gr. W. KRAFT, of Philadelphia, in the county ofPhiladelphia, in the State of Pennsylvania, have invented a new andImproved Method of Constructing the Cup for the lVater-Lute ofGasolneters; and I do hereby declare that the following is a full andexact description thereof, reference being had to the accompanyingdrawings and to the letters of reference marked thereon.

The same letters refer to like parts.

Figure 1 is an elevation of telescope gasometer, Fig. 2 and Fig. 3transverse sections of the same, in which the improved V cup is shown onthe inner section, and the ordinary square cup on the outer section, ofFig. 2, and the V cup is shown on both the inner and outer sections ofFig. 3.

a is the shell of upper section, Z), the shell of lower section, 0,angle iron legs, d, angle iron rings of cup, 6, stay irons to strengthencup, f, bead iron on edge of cup, 9, plate ring of square cup, 71, cuprim.

In the construction of my improved cup, or lute, I dispense with theplate ring g, and one of the angle iron rings (Z, and by a single courseof rivets secure the shell, angle iron ring, and the cup rim firmlytogether, or if preferred, the plate ring, and the angle iron rings mayall be dispensed with and the shell, and cup rim be riveted together asshown by the upper section of Fig. 8. By this arrangement and form ofcup, or lute there is great economy of construction, and much lessweight of iron, while at the same time the weight of water is greatlyreduced, but one half the quantity being required.

It will readily be perceived that my improved V cup may be used withequal facility, whether applied to both sections of the gasometer, or toone section only and working in connection with the ordinary square cupon the other section.

Having thus fully described my invention, and the mode of applying it, Iwish it distinctly understood that I do not claim the ordinary squarecup represented by the outer section Fig. 2, but

\Vhat I do claim as new, and desire to secure by Letters Patent is- Theconstruction, and application of the V shaped cup or lute whether asshown by the inner section Fig. 2 or by the inner or outer section Fig.3, and this I claim whether it be accomplished precisely as hereindescribed, or in any manner equivalent thereto, producing substantiallythe same result.
